multiple curl call to the same url

[gokberx]

I want to build hits engine that simulate users hits to specific Url,I use \[code\]curl_exec\[/code\] call to the same url in a loop.How can I improve the performance of this script ?What is the right way to do this ?What i do until now is :\[code\]$options = array( CURLOPT_RETURNTRANSFER => true, // return web page CURLOPT_HEADER => true, // return headers CURLOPT_FOLLOWLOCATION => true, // follow redirects CURLOPT_ENCODING => "", // handle all encodings CURLOPT_USERAGENT => $useragent, // who am i CURLOPT_AUTOREFERER => true, // set referer on redirect CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect CURLOPT_TIMEOUT => 120, // timeout on response CURLOPT_MAXREDIRS => 1, // stop after 1 redirects CURLOPT_URL => $url . $fields_string, CURLOPT_SSL_VERIFYPEER => false, ); //open connection$ch = curl_init();for ($i = 0; $i < $NumberOfHits; $i++){ curl_setopt_array($ch, $options); //execute post $result = curl_exec($ch); if(curl_errno($ch)) { $error = "Curl error: " . curl_error($ch) . "\n"; fwrite($fp, $error); } $returnCode = curl_getinfo($ch); $my_arr[] = parse_url($returnCode['url'] , PHP_URL_QUERY); ... }\[/code\]I know about curl_multi_exec but this issue is build to different urls, Would it be right to use it in my case too ?
